> Key: SUBMARINE-1278
> URL: https://issues.apache.org/jira/browse/SUBMARINE-1278
> Project: Apache Submarine
> Issue Type: New Feature
> Reporter: Yu-Tang Lin
> Assignee: Yu-Tang Lin
> Priority: Major
>
> Per the discussion with Didi's users,
> they think it might be useful if submarine fetches the data from external file system(ex: hdfs, s3... etc) into cluster first and then the following executions could read the data from local environment.
> After couple discussions, we have couple proposes for above scenario.
> # Once the external data source had been set, submarine launches another container as initialize container of experiment; In this container, we leverage fsspec to fetch data, and persist into apache arrow, then the workers in the execution read the data from arrow directly; In the termination phase, submarine launches another container to clean up the data in arrow.
> # the flow is quite similar to option1, instead of we replace fsspec with alluxio. But due to we're not a hybird cloud environment focusing solution, I think the tech stack of alluxio is too thick for us, so I prefer the option 1 more.
> About the external file system integrating, we'll try to integrate hdfs(w/ kerberos) as our first step.
